[ RadSafe ] Researcher finds revolutionary way to treat eye cancer

Dear all

In principle, this sounds interesting, but in practice, there is no need for this treatment option. All patients with uveal melanoma treated with brachytherapy turning legally blind as a result of the treatment could be treated with proton beam radiotherapy. With this treatment, most of these patients would retain a usefull vision.
The problem is rather that proton therapy is only available in a very limited number of specialized centers and physicians do not like to send their patients to another doctor if they can do something like brachytherapy themselves.

Kind regards
Emmanuel Egger

That is what I assumed.  And it is a wonderful, probably game-changing idea (given that the trials support it).  Bear in mind that I-125 seeds are about an effective energy of 28 keV; Pd-103 seeds are about 21 keV.  So, it is hard to see that the technique would be useful for medium-E photons.  I wonder if it would not be useful for beta emitters though;  there should be minimal bremsstrahlung.

Interesting.  I assume it works by increasing the density of the fluid inside 
the eyeball, thus providing more absorption of the radiation before it reaches 
other structures.
